Hello everyone, Are the maximum SHGC values in ASHRAE 90.1-2007 suggested only? For example on table 5.5-1 there is a max SHGC listed of 0.25.

Our project has 4 garage levels. There are 3-4 elevator lobbies on each level. The lobbies are small and receive OA from RTUs serving the offices above.

If we are asked to provide for 1 point or 50% FSC Wood by cost but are making casework, do we have to ship the casework as FSC certified?

We have a fair amount or T&G wood that is being installed on the Ceiling.

We are in the conceptual design phase of a project consisting of renovations to an existing building and a significant addition.

for example, the project is a large building with a commercial spaces on each floor that will be sold.

In preliminary design review, we had attempted the Brownfields point, which is an option in SSc1.2.1, as well as 4 other points in that credit.

If We have chemical storage room with 69.4 ft square in Area in our building , i want to install one exhaust fan for this room to acheive credit requirements , how can i calculate minimum pressure

What does “Open Bottom Planters” mean? I assume they drain to ground water – and not to a weep hole in the face of the wall, and then to storm? Thanks.

Does LEED allow the modeler to claim savings for increased insulation on either the ductwork, piping, or equipment itself?
